The surface I 0 of the pad is of a width he pad presents two plane surfaces I0 and sufiicient to form a supporting platform for the I I inclined to each other so as to determine a whole mid-tarsal area of a foot as ma be seen wedgelike body. At the line of intersection I2 y from Fig. 1, where the skeletal structure of a the heel bone 40, that is to say, does not covergqq the heel portion 2| of the inner sole l3ofthe shoe. It is important that the platform "I'- afforded by the pad should extend far enough in the transverse direction so as to underlie the tuberosity of the base 5| of the fifth metatarsal 51. This tuberosity is situated at a regionof the; human foot which, when the foot is placed in a conventional shoe,'lies above and beyond the contour line of the sole l3 of the shoe, andit is for this reason that, as mentionedabove the pad is made so as to extend asufficient distance beyond the outer contour line of the shank part of the sole. In this manner, a participation of the base 5| of the fifth metatarsal in the'weight-bearing function of the foot is assured; this base 5| of the bone 5| just resting upon the pad Rwithout being pushed upwardly or sidewardly as has been done by many of the corrective pads heretofore used. 7 1

As may be seen from Fig. 5, the pad P levels out to a very considerable extent the bend which exists in the length profile of the sole of the shoe due to the shank portion thereof, and in its' trans verse sections the pad is level on the upper side alon the whole width of the shank part H of the inner'sole l3 of the shoe (Fig. 6).

It is to be noted that if the pad is made of sufficiently resilient material it may be placed in the shoe with the large surface I0 resting 'on the inner sole [3. By forcing the pad into the shape-in which this surface Hl'will follow the curvature of the inner sole I 3 between the points and 22, the two surfaces II and I6 (now on top) will move into positionsin which theyform a continuous surface corresponding to the surfaceHl'showninFig.5. V

A cover 23 (Figs. 5 and 6) made of, leather or the like may be used to assist in keeping the pad in the desired shape.

It is to be understood that various changes in form, arrangement and material may be made without departing from the spirit of the invention or the scope of the appended claims.

What I claim is:

l. A foot corrective appliance to be worn in a shoe, comprising a pad adapted to be placed above theshan-k-part of thesole of.the;shoe-so as to cover this'shankpart atiall points, saidpad having a central longitudinal section substantially in the shape of a triangle and cross-sections in the shapeof trapezoids with the shorter of the two parallel'si'des "having a length substantially equal to the widthof the corresponding portion of the shank of the shoe and the longer of the two parallel sides extending considerably beyond the contour line of the corresponding portion of the shank of the shoe, the extending portion of said pad on theouter side when in use underlying the base of the fifth metatarsal bone and providing a transverse level support therefor.

2. A foot corrective appliance-to be worn in a shoe, comprising a pad adapted to be placed above the shank part of' the sole of the shoe so as to cover this shank part of the sole of the shoe at all points, said pad, when placed in the shoe, having its central longitudinalsection sub stantially in the shape of atriangle in which the longest side forms the top side whereas of its two other sides the one is adapted to extend from the meeting point of the forepart of the sole of the shoe with the shank along said shank to approximately the heel and the other'i adapted to extend from'said meeting point along the forepart of the sole'over a portiononly'of the latter, and said pad having cross-sections in the shape of trapezoids with the shorter of the two parallel sides of each trapezoid being the lower' side and having a length approximately equal to the width of the corresponding. portion ofthe shank of the shoe and the longer of the two parallel sides of said trapezoids being the top side and extending considerably beyond the contour line of the corresponding portion of the shank of'the shoe at the side corresponding to the outer side of the shoe as to provide in use a transverse level support for the base of the'fifth-metatarsal bone.
